It’s more common to find that stone age humans lived under rock outcroppings than caves proper as it happens, partly because it is much more common to find an outcropping than a sufficiently large cave. They also simply didn’t have many permanent settlements until the development of agriculture so either way the groups wouldn’t stay long
More common than both is indeed wooden and leather shelters, but you don’t find surviving paintings on leather from 50,000 BC
